Learning Scrapy today suddenly encountered this problem, a few days ago when created good, questions have been settled in baidu, but a bit don't understand why "d: \ BLD \ scrapy_1572360424769 \ _h_env \ python exe" this find python. Exe, I haven't had this disk folder
I have gave him a virtual environment created, shouldn't be in the C: \ Users \ WustAnt \ AppData \ Local \ Continuum \ anaconda3 \ env here find python exe?


Bosses under the guidance of, looked on the Internet also did not say why to appear this situation only solution

CodePudding user response:

In your current command line input:

 
Python - version 

Look at the current command line terminal is found in the python you want version,

In addition to

 echo PATH % % 

Will see if, in the current PATH environment variable, not careful, contains, what you don't want to:
D: \ BLD \ scrapy_1572360424769 \ _h_env \
Such as, the relevant path,

In addition, in your code to print out

 
The import sys 
Print (" sys. The executable=% s "% sys. The executable) 

Said the python interpreter the full path of the

What seems to be:
You just created a virtual environment, but did not enter=start=enabled this virtual environment???????

Windows into the virtualenv virtual environment, in general is:

 venv \ Scripts \ activate bat 

So: you first make sure you entered the indeed, already in, a virtual environment

At this point, the command line the front will generally have a prompt: (venv)
To run your scrapy:

 scrapy XXX XXX

Have tried,

Sys. The executable=C: \ Users \ WustAnt \ AppData \ Local \ Continuum \ anaconda3 \ envs \ spy_env \ python exe 

Path has seen it is not similar, but used the practice of virtual environment created by the same operation is no problem, feel my environment create problems

refer to the second floor crifan response:

Though don't know what happened, the scrapy unloading, use PIP reinstall again good, before is made from conda is installed
